Cardiac amyloidosis presenting as pseudo-hypertrophic cardiomyopathy.

Both cardiac amyloidosis and hypertrophic cardiomyopathy may result in excessive hypertrophy of the myocardium, which can be seen on echocardiography. While in most patients the two conditions are easily differentiated, we present in this report a case of amyloidosis that mimicked hypertrophic cardiomyopathy so closely that it required endomyocardial biopsy to establish the diagnosis.
